Change in State of Delivery (CISD) is a price-action concept used by traders to identify a potential shift in the way price is being delivered through the market. It is commonly discussed within Smart Money Concepts (SMC) and ICT-style trading approaches. CISD focuses on changes in short-term order flow that may indicate that buyers or sellers are gaining control.

A bullish CISD generally occurs when price changes from delivering lower prices to delivering higher prices with stronger bullish momentum. Conversely, a bearish CISD occurs when price shifts from delivering higher prices toward lower prices. Traders typically observe candle behavior, displacement, liquidity movements, and key price levels to determine whether the delivery of price has changed.

CISD can be particularly useful after a liquidity sweep. For example, price may first take out a previous low before showing strong bullish displacement. This change in delivery can suggest that the market may be transitioning from bearish to bullish order flow. Traders may then look for additional confirmation, such as a Fair Value Gap (FVG), Order Block, or market-structure shift.

One important point is that CISD should not automatically be treated as a guaranteed reversal signal. Markets can produce false shifts, especially during volatile conditions. Traders should therefore combine CISD with broader market context, higher-timeframe bias, liquidity analysis, and appropriate risk management.

In practice, CISD is best viewed as a framework for recognizing changes in price delivery rather than a standalone trading strategy. By studying how candles move and close around important liquidity and structural levels, traders can use CISD to improve their understanding of market momentum and potentially identify higher-probability trading opportunities.

Change in State of Delivery (CISD) is a technical concept that traders use to spot possible changes in market momentum and direction. It focuses on the relationship between price movement and the opening levels of significant candles. When price violates an important level associated with the previous direction, it may indicate that market control is beginning to change.

For example, if sellers have been dominating and price subsequently breaks above the opening of a key bearish candle, traders may consider this a bullish CISD. In contrast, a break below the opening of a key bullish candle can provide a bearish CISD indication.

Many SMC traders use CISD alongside liquidity raids, Order Blocks, Fair Value Gaps, displacement, and market structure analysis. These additional factors can help determine whether the signal has meaningful context. CISD should be viewed as confirmation rather than an automatic entry signal, because markets can produce false breaks and temporary reversals.
